Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

How to use #2fcffe

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #01627F
Safe as a 1px border on white
No — use #01A1D0

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

cleantechnicalfreshclinical

Cyan reads as water, air and infrastructure: cool, hygienic, engineered.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The mid lightness keeps it versatile in both themes.

Worth knowing

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

#2fcffe, answered

What color is #2fcffe?

#2fcffe is a balanced electric cyan, closest to Deep Sky Blue (ΔE2000 6). It sits at 194° on the hue wheel with 99% saturation and 59% lightness, which reads as cool.

What is the RGB value of #2fcffe?

rgb(47, 207, 254) — 47 red, 207 green and 254 blue out of 255, or 18.4% / 81.2% / 99.6% by channel.

What is #2fcffe in HSL and HSV?

hsl(194, 99%, 59%) and hsv(194, 81%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2fcffe a light or a dark color?

It is a light color. Relative luminance is 0.5239 and perceived brightness is 71%, so black text on it reaches 11.48:1.

Should I use black or white text on #2fcffe?

Black. It scores 11.48:1 against #2fcffe, versus 1.83:1 for white — AAA at any size.

Is #2fcffe accessible on a white background?

#2fcffe on white scores 1.83:1, which fails WCAG AA at every size. Darken it to #017EA2 to reach 4.5:1, or #015E7A for 7:1.

What is the complementary color of #2fcffe?

#FE5E2F sits directly opposite on the wheel. Softer options are the split-complements #FE2F68 and #FEC52F, which give the same contrast with far less vibration.

What colors go well with #2fcffe?

For interface work: #F4F9FA as the surface, #C0E2ED for borders, #4B899B for secondary text, #FF2E33 as an accent and #01627F for hover and pressed states. For a palette, the analogous pair #2FFEC5 and #2F68FE stays calm, while #FE5E2F is the loudest partner.

What is #2fcffe in CMYK for printing?

cmyk(82%, 19%, 0%, 0%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #2fcffe warm or cool?

Cool — it scores 93 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2FFEE1; nudged cooler, #2EB1FF.

Which Tailwind color is closest to #2fcffe?

The cyan family — its 500 step is #06b6d4, ΔE2000 8.2 away. That is a visible difference, so define #2fcffe as a custom token rather than reaching for the built-in.

How do I use #2fcffe in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2fcffe] or text-[#2fcffe], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #2fcffe with 50% opacity?

rgba(47, 207, 254, 0.5), or #2fcffe80 in eight-digit hex. Over white that composites to #97E7FF; over black, #18687F.

Is #2fcffe a web-safe color?

No. The nearest web-safe colour is #33CCFF, ΔE2000 1.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #2fcffe mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #2fcffe?

The safest is same-hue elevation: linear-gradient(135deg, #6CDDFE, #2fcffe 45%, #01627F). For more colour, a short hue run to #1016FE keeps it rich without turning muddy.
